WAGON-STANDARD.

' Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed October 26, 1904. Serial No. 230,043.:

`To all whom t may concern:

Be it known that I, WALTER E. SNoDGRAss, a citizen of the United States,residing at Hull, in the county of Pike and State of Illinois, haveinvented a new and useful lagon-Standard, of which the following is aspecification.

The invention relates to improvements in wagon-standards.

The object of the present invention is to improve the construction ofwagon-standards and to provide a simple, inexpensive, and efiicientdevice of great strength and durability adapted, in the event ofwagon-beds, racks, loads of lumber, wood, cc., being loose, to enablethe same to be tightly clamped and securely held on the running-gear.

A further object of the invention is to provide a device of thischaracter which is capable of convenient operation to engage and releasea load and which will be entirely out of the Way when not in use.

Y With these and other objects in View the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion, size, and minor details of constructionwithin the scope of the claims may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure lis an elevation of a bolster and a pair ofstandards provided with clamping devices constructed in accordance withthis invention. Fig. 2 is a vertical sectional View of one of theStandards and the Fig. 3 is a horizontal sectional view on the line 3 3of Fig. 2.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l l designate standards arranged at the ends of a bolster 2 in theordinary manner and designed to be constructed of wood and provided witha metal strip or band of the usual construction; but the standards maybe constructed in any desired manner, as will be readily understood. Atthe inner faces of the standards are arranged vertically-disposedclamping members consisting of plates or bars 4, which are connectedwith the standards by adjusting-screws 5, whereby they are adapted to bemoved inward and outward to zlarrp and release a wagon-bed, rack, or aThe adjusting-screws, which may be of any desired number, are preferablyarranged at the upper and lower portions of the standards, and theyengage threaded perforations of the metal strap or strip 3; but thescrew-threads of the standards may be provided in any other desiredmanner. The outer ends of the adjusting screws are provided with heads6, which may be of polygonal form to receivea wrench, or any otherdesired form. The inner ends 7 of the screws are reduced and passthrough perforations 8 of the upright clamping members, and after theparts are assembled the reduced ends 7 are headed, as shown at 9, toretain the clamping bars or members on the inner ends of the screws. Bythis construction the inner ends of the screws are swiveled to theclamping-plates and are adapted to rotate on the same.

The-clamping bars or membersare adapted to lie iiat against the innerfaces of the vertical standards when the clamping devices are not inuse; but when the wagon body or bed is removed and a loose load placedon the running-gear the said load may be firmly clamped and securelyheld in place. Also in the event of a loose wagon bed or body or hay orstock rack the same may be firmly clamped on the running-gear. Theclamping bars or members are engaged by the shoulders formed by reducingthe inner ends of the screws, so that the reduced outer ends are notsubjected to the strain incident to the clamping action of the bars ormembers.

It will be seen that the device is exceedingly simple and inexpensive inconstruction, that it is adapted to be readily applied to the ordinaryvehicle-standards, and that it is capable of firmly clamping aWagon-box, rack, or load on the running-gear and of readily releasingthe same. It will also be seen that the adjusting means, which force theclampingplates inwardly, serve as the means for supporting thesame.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination of a standard having threaded apertures, adjusting-screws mounted in the threaded apertures of the standard, and aclamping member carried by the clampingscrews in their inward andoutward movement IOO and being positively forced inwardly by the saidscrews to Clamp a body, rack or load.

2. The combination of a standard having threaded openings, a verticalclamping-plate arranged at the inner face of the standard, andclamping-screws mounted in the threaded openings of the standard andextending entirely through the same and having their inner ends swiveledto the clamping-plate,

IO whereby the latter is supported in positionfor engaging a body, rackor load, said clamping-screws being adapted to positively force theclamping-plate inwardly.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
